Each point can be identified by an ordered pair of numbers; that is, a number on the x-axis called the x-coordinate and a number on the y-axis called the y-coordinate. Ordered pairs are written in brackets (x-coordinate, y-coordinate).
X and Y coordinates help identify a point in the coordinate axes and are written as (x,y). The coordinates of a point are denoted as (x,y), where x represents the position of the point with respect to the x-axis and y represents the position of the point with respect to the y-axis.
x, y coordinates are the horizontal and vertical addresses of pixels or addressable points on a computer screen.
Coordinates are written as (x,y), which means that the point on the x-axis is written first, followed by the point on the y-axis. Some children can be taught to memorize this with the phrase “down the corridor, up the stairs” which means they should follow the x-axis first and then the y-axis.
The y=x line would appear when graphed on a graphing calculator as a straight line intersecting through the origin with a slope of 1.
Its coordinates are Latitude: 41° 56′ 54.3732″ N, Longitude: 87° 39′ 19.2024″ W. To read it, start with the first group of numbers or latitude. This line reads 41 degrees, 56 minutes, 54.3732 seconds North. The longitude is 87 degrees, 39 minutes, 19.2024 seconds West.
